Patented Apr. 7, 1931 PATENT OFFICE GEORGE W. 03TH, F PHILADELPHIA, PENNSYLVANIA METAL FLASHING Application filed December 23, 1929. Serial No. 415,948.

This invention relates to improvements in building constructions and has particular reference to an interlocking metal flashing which may be used, either as a bonding material between the courses of masonry, or may be used as a waterproofing material beneath copings or the like.

The object of the invention is to provide a flashing of sheet material which, when interposed between two courses of masonry, will form a mechanical bond in the mortar between the courses so as to prevent any slipping, or displacement of the adjacent courses. A further object of the invention is to pro-: vide a flashin' and which, w en bent, will form a perfect bond, thus insuring stability of construction.

According to the invention the metal plate or strip of any size, shape and dimension, is

provided with foraminous metallic sections secured to the face of the metallic strip in such locations and at such points as is desired or required, while the ends or edges of the metal strip or plate are so formed as to interlock with-the adjacent plate or strip. The drawing illustrates an embodiment of the invention and the views therein are as p follows Figu re 1 is a cross-section of a building showing a coping surmounting a brick or stone wall with my improved flashing between the wall and coping; Figure 2 is another form of building construction, showing my invention applied to awaterproofing plate, I Figure 3 is a plan view of one form of plate, and

Figure 4 is a side view of the same. The plate 6 may be of any thickness or shape. In the view which I have shown, one

end of the plate is upturned, as at ,while the other end 8 is downturned, each providing a space 9 for the turned edge of the ad acent plate.

The plate is provided on its upper and lower bottoms, if desired, with foraminous metal sections 11 and while I have shown the same in a certain relation in Figure 3 and in Figure 4 have shown the same as being placed on both the top and. bottom of the plate 6, I do which may .bebent to shape waterproofing plate 14 and this not limit myself to any form, nor to the use of same on both the top and bottom of the plate, but for convenience in the drawing, have shown the sections as arranged in staggered relation.

The sections shown in the drawing are made of expanded metal and, as illustrated, are intended to be braised or welded to the plate 6, but any feasible manner of connection is contemplated within the scope of my invention, such for instance, as attaching the said sections to the plate by means of solder, rivets or the like.

Figure 1 shows a plate which extends between the upper part of the masonry 12 and the coping 13. This plate which extends lengthwise along the top of the said masonry, being interlocked at its ends as before explained, provides a perfect mechanical bond with the usual layer of mortar which is emloyed as a binding agent so that there may e no slipping of the coping from its position on the top of the wall.

' The form shown in Figure 2 includes a plate is for the purpose of insuring the stability of the arts so as to provide the air pocket 16.

The sections are located along the horizontaljoints 17 and 18 and will positively prevent the masonry from slipping so as to close the air pocket.

While Figures 3 and 4 are intended to illustrate the use of expanded metal, I do 7 not limit myself to any particular type of foraminous material, but screen, chicken wire or other-material may be used for the sections which I secure tothe plate.

Of course, the flashing illustrated may be modified in various ways without departing from the invention herein set forth and hereafter claimed.

The invention is hereby claimed as follows:

1. A construction member, cbmprising a flat sheet of metal, and expanded metal sections applied against the faces thereof and securely fixed thereto.

2. A flashing, comprising a flat strip of sheet material having secured thereto sepa rate sectionsof foraminous material, and

means on the end ofsaid strip for interlocking the adjacent strips. 7

3. A flashing, comprising a flat strip of sheet material, and separate sections of foraminous material secured in parallel relation and contiguous thereto.

4:. A flashing, comprising a flat strip of sheet material, separate sections of forami- ,nous material secured in parallel relation and contiguous thereto, and means on the end of said strip for interlocking the adjacent strips.

In testimony whereof I have signed my name to this specification.

GEORGE W. ORTH.
